Application filed April 2,

ble hemp shredding device which can readily taken down and carried to any desired part of the field and set up for operation.

It is a further object of the invention to y provide a'hemp shredder which embodiesv a scraping or shreddingblade yieldably held into engagement with the hemp to be shredded, the latter being so arranged as" to permit'the blade to be held against the iibre with any degree of pressure to shred. theibre into line or coarse shreds as desired.

Another object v.of the invention provides a portable hemp fibre .shredding device which employs a pivoted scraper blade which is held against the iibre by a spring element under tension, the tension of which may be varied whereby the iibre will be vshredded to the desired degree.

With the preceding and other objects and advantages 1n mind, the invention consists inthe novel combination oi elements, construction and arrangement of parts and operations which will be hereinafter enlarged upon, claimed and illustrated in the accompanying drawings, Vwherein Figure 1 is an elevation of the devicel in operation;

Figure 2 is a view taken on line 2`-2 ot` Figure 1;

"Figure 3 is a vertical sectional view taken on line 3--3 of Figure 1;

Figure 4L is a similar view taken on line 4--4 of Figure 1;

Figure 5 is a fragmentary elevation of the device;

` Figure 6 is an enlarged detail view oi the scraper bladeand its mounting; and

Figure 7 isa modied form oftension device embodied in the invention.

Referring in detail to the drawings per ends ot 'the upright-s i921. serial no. 457,961.

wherein like characters oi reference riesig nate like parts throughout the several views. the numeral 5 denote-s a` pair" of vertical uprights upon which a .supporting bracket is detachably supported 'ihis supporting bracket is et U-shape and the legs ther-coi terminate in hooks 7 which embrace the upiet screws i are carried by the ends ci? the U-shaped ybracket and engage the uprights to hold the bracket in place thereon. Extending vertically from one'oi the hooks 7 is a. shank 5 9 and arranged in spaced relation thereto in transverse `alignment on this hook is an upstanding pin 10.

A work block, designated at 11, has one end disposed between the shank 9 and pin 10 while its opposite end is held in place by bolt 12carried by the adjacent part .Ot the frame or supporting bracket 6 and passing through this end oi' the block, a wing nut 13 being threaded on this bolt. The shredding or scraping kni'te is designated in its entirety at 1li. This knife is provided with cutting edges 15, each ot which is ot a diiterent degree ot sharpness. lhewknii'e la is provided with a channel shaped member 16 in which one end oi? a relatively long resilient bary 17 secured.

Embracing the shank 9 is a clamp 18 formed with an outstanding pivot 19 passing through the knife la at its approximate center. ifi wing nut 2() is threaded on the pivot 19 to hold the knife la against lateral movement. Supported on the shank 9 a vertical pole 21 to the upper end ot' which a flexible element 22 is attached. There is provided a tension device whereby' the pref'- sure of the scraper. blade 14 may be varied which consists oit a stirrup 23 having its ends pivotally connectedwith the free end oi the resilient bar 17 as at' 24s. ik turn-lnickle 25 is engaged with the stirrup 23 and carries a ring 26 at its opposite end to which the lower end ot the flexible element 22 is tached. This turn-buckle is toi-med with an eye 27 in which a hand-grip may be engaged to operate the turn-buckle to regulate the tension of the resilient bar 17.

Suspended from the resilient bar 17 in proximity to the channel shaped member 1G is a flexible element 28ql the lower end. ot'

its pivot away from the block 1l.

Normally the free end of the t-readle 29 is disposed above the ground and is adapted to be rocked? downwardly as shown in Figure 1 to move the scraper blade le away from the block l1.

In operation the hemp placed upon the block 11 and the treadle actuated top lex the bar 17 which causes the knife la toinove ou Upcn releasing the ti'eadle the resilient bar "i7 uponA returning to its normal position. returns thescraperblade orkiiii'e and holds the saineY under tension against the hemp which then drawn between the block ll and the cutting edge'oi' the knife.

'lin FigureA 7 a inodifiedY en'ibodiinenj o'l tension regulating device is shown. and includes a substantially elliptical iframe ill having guide openings 32 at its opposite ends.v A flexible element 33 is secured to one end of the frame and its opposite end adapted AforA connection to the upper end otthepole 21. A second flexible element 34- passedy tliroiigfh the guide opening 32 at the opposite end oi thetigame and is adapted to be connected with` the free end of the resilient bar 17. A stern 35 is journaled in the frame at its center to which the inner end of the Flexible element 84.' is attached and is adapted to be wound therearound. Ogiie end of the stern 35 is formed with aneye36 in whiclia handle 37 is' engaged. The flexi ble element 33,is Aprovided with a loop 3S adapted to vengageoiie end of the handle 37 afterthe stein Vhas been operated to wind the 'tienibleeleineiit 345; on the stein 35 t-olhold the stem against 1 rotation.

vIt is to be understood that the forms ot my invention lierein'shown and described are; to vbe taken as preferred examples of the salme7 and that various changes in the shapes, sizes and arrangement of partey maybe resorted to without departingiroin the, spirit of fthe invention or the scope of the sub- `joined claims.
